Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-285: Improper Authorization, where the product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. In Github.com/openfga/openfga, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Overview OpenFGA v1.8.4 or previous (Helm chart < openfga-0.2.22, docker < v.1.8.5) are vulnerable to authorization bypass when certain Check and ListObject calls are executed. Am I Affected? If you are using OpenFGA v1.8.4 or previous, specifically under the following conditions, you are affected by this authorization bypass vulnerability: - Calling Check API or ListObjects with a model that has a relation [directly assignable](https://openfga.dev/docs/concepts#what-is-a-directly-related-user-type) to both [public access](https://openfga.dev/docs/concepts#what-is-type-bound-public-access) AND [userset](https://openfga.dev/docs/concepts#what-is-a-user) with the [same type](https://openfga.dev/docs/concepts#what-is-a-type), and - A type bound public access tuple is assigned to an object, and - userset tuple is not assigned to the same object, and - Check request's user field is a userset that has the same type as the type bound public access tuple's user type Fix Upgrade to v1.8.5. This upgrade is backwards compatible.
